Jennifer Lopez Rocks A Bikini On Instagram

It's hard to believe, but Jennifer Lopez turns 45 on Thursday. You'd never know it from looking at her rocking this bikini on Instagram (link below), but when you've got a ton of money, you can hire personal trainers and all that to make sure you keep that ass in business. 

I think 45 is a good time to hang up nicknames like JLo as well. Can we stop with that now please? It's time to put away childish things like nicknames and start acting like a grown-up when you hit your mid-40s.
